Title: Hot temperature ash transporting method
Inventor: FUJIMOTO AKIHIKO
IPC: F23J3/06
Filed: 1987-01-22
Abstract: PURPOSE:To apply a real heat got by a discharging gas through its transportation of hot ashes as heat for a heat exchanging operation and reuse the heat by a method wherein at least a part of the discharging gas of the heat exchanger is taken out to transport the hot ashes and separate the ashes from the discharging gas, thereafter the discharging gas is mixed with another discharging gas before the heat exchanging operation. CONSTITUTION:Discharging gas generated by a boiler 6 heats air and the like with a heat exchanger 7 to perform a heat exchanging operation, thereafter the discharging gas is fed to a chimney or gas processing device such as a desulfurizing device through an induction fan 8. A part of the discharging gas outputted from this induction gas 8 is taken out, its pressure is increased by a pressure increasing fan 2, then it is passed through an ejector 3 to receive hot ashes from a hopper 1 and to transport it. Then, the ashes and the discharging gas are separated by a cyclone 4 to each other, the ashes are stored in an ash tank 5 and in turn the discharging has is mixed with the discharging gas before its heat exchanging operation. With this arrangement, the real heat of the discharging gas through transportation of the hot ashes is used again as a heat for use in performing a heat exchanging Operation such as an air heating as found in the heat exchanger 7.

Title: Stress corrosion cracking preventing method and its welding structure for weld zone
Inventor: YAMAUCHI KIYOSHI
IPC: B23K9/04
Filed: 1993-01-27
Abstract: PURPOSE:To relax high residual stress generated on a final weld bead, to increase an elastic limit by generation of carbide, etc., and to prevent stress corrosion cracking in the corrosive environment in welding structure of a nickel- base high alloy made of multilayer weld beads. CONSTITUTION:After a welded joint made of the multilayer weld beads 1-6 is formed by using welding material (the Ni-base alloy, for instance) where the carbide is separated out by heating or thermal effect above 1000 deg.C to increase the elastic limit, heat treatment to heat the final weld bead part above 1000 deg.C is carried out. Consequently, the residual stress of the final weld bead part having the high residual stress can be reduced, besides, the elastic limit of the material by separating of the carbide is increased and the resistance force to stress corrosion cracking can be secured.

Title: Screw joint having excellent heat resistance
Inventor: TSURU EIJI
IPC: F16L15/04
Filed: 1994-02-04
Abstract: PURPOSE:To enhance the heat-resistance by forming a surface film having a hardness which is less than that of the mother material, on at least a metal sealing part of either one of a pin and a box, and by setting the thickness of the film to a value greater than the surface roughness of a metal sealing surface. CONSTITUTION:A box 1 and a pin 2 are engaged with each other by threads 4. In a metal sealing part 3 having a substantial sealability, either one of boundary contact surfaces of the pin and the box is formed thereover with a covering film layer 5. During screwing of the joint, the outer surface of the mother material opposed to such a surface treated layer slides. Setting the hardness of the surface treating material to a value less than that of the mother material, is an indispensable term for enhancing the heat resistance, in addition to the combination of the film thickness and the surface roughness. The film thickness of the surface film 5 is set to a value greater than the surface roughness of the slide surface opposing thereto, and further, the hardness of the film is set to a value less than that of the mother material, thereby it is possible to exhibit a sufficient heat-resistance.

Title: Slave station transmission system of time division multiplex multi-direction communication system
Inventor: TAKAHASHI KIYOAKI
IPC: H04J3/00
Filed: 1981-01-30
Abstract: PURPOSE:To realize the good communication, by giving a sum logical operation to a phase reference symbol formed with a mark after adding a time division multiplex signal to the said symbol to supply the symbol to a 2nd-phase differential phase modulator and at the same time carrying out a gate process at the valley part of an envelope curve of the modulated wave. CONSTITUTION:A clock speed modulating circuit 1a and a phase reference bit adding circuit 1b are provided at the front stage of a sum logical circuit 3 and in the circulating direction of the signal, and a mark which is delivered from a burst gate signal generating circuit 9 as a phase reference symbol is added to a time division multiplex signal. The artificial random code added with the above- mentioned mark receives a sum logical operation and is supplied to a phase modulator 5. Thus the 4-phase differential phase modulation is given to the carrier wave. This modulated wave receives a gate process through a burst gate circuit 8 based on the burst signal to be transmitted toward a master station. Accordingly the undesired spectrum is suppressed instantaneously to give no evil effect to other circuits because the burst gate process is carried out at three points whe the amplitude is set at zero.
